Templates (0)

The library lists no templates for this return.

EU return: the templates and instructions are defined by the EBA. See the library's EBA entry eba/dora (docs/eba/dora.md). Irish firms use the EBA's templates and taxonomy. Source

Validation rules

The CBI publishes the checks it runs on this return. They could not be counted from the published material. Software can run them exactly as published. Source

How they are written: EBA validation rules in the EBA reporting framework (see the EBA entry); Portal taxonomy checks and variance analysis.

The rules are the EBA's (see the library's EBA entry eba/dora). The Portal also checks the file against the taxonomy (blocking errors), runs non-blocking checks and, for some templates, a period-on-period variance analysis that firms must explain before sign-off.

How they were counted

Not counted here: the EBA's validation rules apply (see eba/dora).

Counts are in the CBI's own unit, so they are not comparable with other regulators' counts.

Public data

No published data from this return was found. No data from this return published by the Central Bank was found on the pages checked. Source
